Very classy 🙄

I know a lot of people could care less about this tradition but it's just considered rude to wear a white dress to a wedding if you aren't the bride. And it's not so much that someone maybe didn't know; it's never some random guest or friend. It's always the MiL or another in-law who does it as sort of a dig at the bride.

wearing white at someone else's wedding is really tacky. So though it may be hard as hell, I think the best thing you can do is not to let it get to your hard, and instead let them expose themselves as the nasty idiots they are to the rest of the guest. If you cannot manage that, an "unfortunate" situations involving a glass of red wine may save the day...

Your not supposed to wear the same color dress as the bride regardless of that being white, green, purple, ect.

The whole "white wedding dress" started with Queen Victoria at a time when the royalty's finances and the nation were in a time of austerity. The white dress cut down on costs. As most people have innate sheep-like tendencies, especially when insecure, other have followed suit every since. Over the years, I have asked my friends and acquaintances what advice they would give their younger selves about their weddings. It's almost always a variation of the following: "Spend less on the wedding and use the money to minimize debt or pay for help; not sweat the small stuff at the wedding so they could actually enjoy it and realize that the friends and loved ones at the wedding are people you want in your life, so who really cares about these little missteps. A wedding is not some kind of competition, it's a celebration."

Murder time!😈

I didn't want anyone wearing white to my wedding either but did not think I needed to state that. My grandmother showed up in a white suit with ankle length skirt, and as usual when she had it altered she had the excess made in to a cover for her cane (cane always matched her outfits). I did not give a hoot when I saw her on the day, and there are people who still 26 years later talk about how classy she looked with that matching cane cover.

who cares. they are just regular dresses

Seems like a lot of people here are missing the fact that when the matrons and/or sisters wear white at another woman's wedding this is a deliberate atttempt to hijack the occassion, or, to at least comp some of the attention.

Ew

Sometimes that's what the bridal couple asks for though. There is a rising number of wedding parties who wear white or beige as a trend. I know it's not global though.

It also is a color of prosperity and good luck in some countries. Cultural reasons. Not the full story.

why is this a problem? why would they be mad? who cayes what color other people are wearing.

If you are three type of person who is focused on looks that this spoils the celebration of your love and marriage with friends and family, you have only yourself to blame. In the big scheme of things this is a tiny blip so don't let it spoil all the positive aspects of this special day.

My cousin got married in the late 80's and every woman in the wedding party, including myself who did the guestbook, was asked to wear white. It was a beautiful event. That might have been the case here.
